@joeycastillo , Hi thanks for the additional info. I looked at the Orea’s also and see your point. My pre amp has 8 signal tubes and I definitely want to isolate it with large amps and pending subs. I’m planning on being able to shake the house. I plan on putting a lot of effort into isolating my pre and my TT. Probably a lesser cost factor on my power amps. My pre is Rogue Hera II, it’s large with a separate power supply that is usually run stacked. I’m looking at building my rack and considering how to set the Hera. Due to size and heat it will probably be on the top shelf near my TT. I can put it on a platform on top of the shelf. Or I can isolate by something underneath the power supply and adding something between the power supply and the pre above. Then I can go full bore and add 8 tube dampers also. So many choices and it gets expensive. Gotta love First World Problems , makes me grateful for what I have. Anyway, thanks for your help , Mike B.
Footers under new speakers
Hi , I’m seeking advice regarding footers and/or platforms under my speakers. I purchased Tekton Double Impact’s and have heavy shag carpet and padding over a cement slab floor. House is 35 years old, cement is thick and well cured. I’m from that old mindset of spikes into cement and I am looking for an improvement. I’ve looked online at Gaia footers and Herbie's Studded Giant Gliders. I emailed Herbie’s and specifically inquired about the studded gliders alone on the DI’s over carpet. I asked about stability and was told the speakers were “ heavy enough “. Unfortunately I just set up the DI’s temporarily to get a little break in time. They are without any footers upright on my carpet. At 115 lbs the speaker does about zero to compress the carpet. I understand weight Vs footprint is abysmal but they won’t even stand straight. I’ll probably put the spikes on for a bit until I formulate a plan. But my first concern is that Herbie’s gliders alone are not enough and due to the minimum cost of the speakers I am struggling with purchasing Gaia’s footers and footer spikes. The seismic stands look exceptional, but I’m trying to be frugal. So I’m looking for suggestions like, gliders or dots with or without spikes on wood / stone plinths spiked to the floor. My goal is to try some sort decoupling (Gliders / Springs / Dots) AND eliminate the need of having to rely on the carpet being compressed. And yes I have cheap speakers and seek a cheap solution, so I get that limitation. Unfortunately I can’t afford Tannoy’s or Fynes to compliment my 180 watt tube mono blocs for at least a year. Cheers , Mike B.

MDF is not the material being suggested. MDF has a very poor measuring Damping / Dissipation of 0.017. 0.017 is a value that has a very very little Intrinsic Property to prevent Transferred Amplitude from migrating through the material. Brands to think about are Panzerholz and Permali. Look at a Taiko DAIZA Sub Plinth, but to not concern oneself with the rebate pattern that is used in their base of the Board. |
The Link showing the Speaker Build shows a method selected as a Sub Support to suspend the Speaker, using a Vibration Control Footer and a Bridging Bar to connect the VC Footers. A little bot of extra though can really tidy these up aesthetically if one needs to have bling with their equipment. https://pinkfishmedia.net/forum/threads/my-troels-gravesen-the-loudspeaker-3-build.303400/ The Link is showing the designs available from the Producer of the VC Footers seen in use. https://www.christiegrey.com/industrial/enclosed-spring-mountings/ My suggestion is that if such a methodology is selected, the following can be considered: 1, Look to see if the devices can be attached directly to the Speaker Base, an adapter thread used in place of the bolt on the top of VC Part, can be looked into to see if a Thread Size can be put in place to match a threaded insert found in the base of a Speaker. 2, A Sub Plinth could have 3 x VC Footers attached. 3, If Bridging Bars are wanted to be selected, using metal only is suggested to be avoided. A Composite of materials can be used, that includes a metal. 4, A material such as a Resin Impregnated Densified Wood Board can also be used for the Sub Plinth suggested in '2' or as the Bridging Bar. |
I posted before about StackAudio Auva 70 feet I use on wood floors for ease of moving due to thin felt on the bottom. Spikes are included in three sizes, select your preference, and can be added for carpet. I haven’t been able to find the forum guidelines on posting pictures but am testing something that a search showed. (That was easy if you know how it works on this forum.)

@pindac , Thank you for your recent post. The links are very helpful and definitely give me some ideas. I’m on hold for the next two months due to my house renovations. After that I can break out my gear and get going. I’m planning on building a component rack and will incorporate some of your suggestions. Thank you , Mike B. |
